new member - 1st ? - throwout brg
Hello everyone, glad to join you all. I replaced the clutch with a generic stock package but now have no freeplay at fork with linkage disengaged. It sounds like there are two sizes for throwout bearings long 1.5 and short 1.25. I think it must be a long that I installed. Can someone tell me if 69 positively should have short one?
(69 conv 350/300 4spd red/b/b 3.36 d.d.)
Is possible that you clipped the fork on the wrong side of the bearing flange? I put a LUK in my 69 to get by until QM repaired my performance unit. I notice that LUK has a huge warning on the box and in the destructions that indicates exactly where to clip the fork to the bearing. I was noticing if you clipped it in the wrong spot it would cause travel problems.
I am not aware of different length bearing housings.
Final thing, is there any chance that your bearing mount housing is scored up, grooved, or worn to the point that the bearing is hung up on the shaft?
The fork I have was missing the clip that holds the bearing. I didn't realize this and just slipped bearing on fork loose. I know what your saying about the clip on wrong side but even with no clip I should get some motion/freeplay. The clutch kit was from Pioneer and when I called GM about a bearing they told me about the 1.25 size. When I measure the one that came out, it was about 1.5. But most likely the owner before me ( I've had car less than year) put wrong one on because there is a groove in snout nose peice which indicates bearing was spinning on it which also indicates clip and bearing stop were not working.
So, I'm pulling tranny tonight to fix problem. I bought new fork with clip, new 1.25 bearing just in case and new pivot ball. If bearing I pull out turns out to be 1.25 then I have no idea what the problem is other than bent fork.
Welcome to the forum.....It's a fun place...sounds like you have the problem solved.......Good luck.

You've got the right parts - the 1.25" T/O bearing is the right one. This may be redundant, but make sure you have both the heavy ears of the clutch fork and the spring INSIDE the groove on the bearing; the rear flange on the bearing will fit into the "curls" on the end of the fork, but if it's installed that way, you won't be able to get proper adjustment. Poor design, allows it to be assembled wrong - I see lots of them.
Just final update from this weekend.
Took T/O brg which came with clutch kit out and compare to GM. It was about .100 longer than GM. Also I had installed new bellhousing and didn't notice but the ball stud was longer than the one I had originally. So took long one out, and installed my old short one. Now back on the road and everythings perfect. Knock on wood!
